Revert "Update GreetingHelper.php line 443 to add now required single quotes on key name"

This reverts commit 318f1da3ac021ea6a7c4d4c4838ef949593d0e23 massive whitespace problems caused by the fact that the original files are in MS-DOS format and have CR characters everywhere. Rather than convert formats on an old extension, I'm going to try to comply with the old format by editing on my local machine instead.
